Fans can pre-register for the newly designed refillable cup on the chain's Facebook page.

The 2012 Roo Cup, a refillable cup for fountain and frozen beverages, will retail for $6.99 plus tax. It can be refilled with any fountain or frozen beverage for only 25 cents through Labor Day at the more than 1,600 Kangaroo Express c-stores throughout the Southeast.

Starting May 1, Roo Cup fans can pre-register on the Kangaroo Express Facebook page to reserve a 2012 Roo Cup and unlock an additional week of savings. Pre-registrants will receive a printable certificate with details to redeem in-store and purchase a Roo Cup starting May 16 at 7 p.m. -- one week before the Roo Cup's release to the general public on May 23.

Last summer, 264,000 Roo Cups were available and they sold out in just four weeks. Twice as many cups will be available this summer, and the online reservation system will ensure devoted Roo Cup fans don't miss out on the added value the Roo Cup unlocks this year, the retailer said.

"This is still the same Roo Cup that everyone knows and loves, but it's gotten a serious makeover," said John Fisher, senior vice president of marketing, merchandising and restaurant operations for Kangaroo Express. "We're offering new QR code and text messaging deals to make it easier than ever for Roo Cup fans to stay cool all summer without breaking the bank."

Each newly designed cup has a QR code that customers can scan every Monday to access exciting videos, games and giveaways. Fans can also join the Roo Cup Club by texting "ROOCUP" to "THEROO" (843766) to receive text messaging deals, such as free refill days.

Additional in-store deals on candy, snacks and at participating restaurants inside Kangaroo Express stores will be available to keep the savings flowing all summer long.

Kangaroo Express is also seeking passionate devotees to be a part of this summer's Roo Cup Street Team. Those interested in signing up for the team and receiving free Roo Cup swag to share with their community can visit the chain's website, www.kangarooexpress.com, starting May 1. The Roo Cup Street Team members who generate the best energy and capture their town's excitement for the Roo Cup may have a chance to answer the question, "What would you do with 100 Roo Cups?", according to The Pantry.
